The reliability and validity of the glittre activities of daily living (ADL) test in multiple sclerosis patients

This study was planned to determine the reliability and validity of the Glittre Activities of Daily Living (ADL) Test in individuals with Multiple Sclerosis (MS). A total of 51 patients were included in the study, 25 MS patients in the Relapsing Remiting MS (RRMS) type who scored 4 and under 4 on the Extended Disability Status Scale (EDSS) and 26 healthy participants. For the criterion validity of the Glittre ADL Test, the correlation with the 6-minute walk test (6MWT) was examined. A negative and very good degree of correlation was detected between 6MWT with the Glittre ADL Test (r=-0.710, p<0.001). Patient and control groups were compared for known group validity. There was a difference between the two groups (p=0.001). Test-retest method was used to determine the reliability of Glittre ADL Test. Intra-observer reliability was evaluated by intraclass correlation coefficient (ICC). The correlation (r=0.918, p<0.001) and ICC coefficients (r=0.941, p<0.001) of the Glittre ADL Tests results performed with 3-6 days interval were quite high. In the study group, there was a perfect correlation between Glittre ADL Test and Expanded Disability Status Scale which is used to evaluate the level of neurological impairment (r=0.836, p<0.001), Nottingham Extended Activities of Daily Living Scale which is used to evaluate daily life activities (r=-0.841, p<0.001) and Mini Balance Evulation Systems Test which is used to evaluate balance (r=-0.792, p<0.001), very good corelation between Glittre ADL Test and 5 Repetition Sit To Stand Test which is used to evaluate lower limb muscle strength (r=0.720, p<0.001), moderate correlation between the Glittre ADL Test and the physical health subtitle of Multiple Sclerosis Quality of Life 54 scale which is used to evaluate quality of life (r=-0.591, p=0.002). There was no correlation between Glittre ADL Test and the mental health subtitle of Multiple Sclerosis Quality of Life 54 scale (r=-0.353, p=0.083) and Fatigue Severity Scale (r=0.348, p=0.096). At the end of our study, It was concluded that Glittre ADL Test is a reliable and valid measurement tool in the evaluation of functional exercise capacity in MS patients in the RRMS type who scored 4 and under 4 points on EDSS and can reflect the performance in daily life activities.
